. Application and January 29, 1915. Serial No. 5,017.

To all whom it may concern:

Be it known that we, GEORGE EDWARD HARRISON and'JoHN TEMPLETON, subjects of the King of Great Britain, and residents of the city of Toronto, county of York,'Province of Ontario, inthe Dominion of Canada, have invented certain new and useful Improvements in Heating Systems, described in the following specification and illustrated in the accompanying drawings, that form part ofthe same. v

The principal objects of the invention are to localize the heating equipment in a building, operating the heating apparatus in individual units, thereby efl'ecting, a saving in cost of installation and operation and insuring uniform temperatures throughout.

A further and important object is to eliminate the disagreeable and wasteful features incident to the operation of a centralized heating plant, and to devise a heating equipment which will operate indefinitely without attention;

The principal feature of the invention consists in the novel construction and arrangement of parts, whereby a small body of water is brought into contact with heating surfaces and converted into steam and the steam is directed into a radiator, the

radiator and steam plant comprising an individual unit.

- In the drawings, Figure 1 represents .a

devicezconstructed in accordance with this invention. Fig. 2 is an enlarged longitudinal section of the boiler.

I Referring to the drawing, 1 is a radiator ';-.:.-;which may be of any suitable desi an opening 2preferably arranged in the bothaving tom thereof.

3 .is a pipe arranged within the radiator and'connected centrallyfof its" length by a suitable nipple to the opening 2. The outer ends. 4 of the pipe 3 are turned upwardly a short distance. p

- 5 is a steam boiler of miniature design preferably of cylindrical form having tubes -6,"only one of which shows in the section,

arranged adjacent to the bottom and extending from end to -end, 'the ends thereof extending-through suitable packing glands to allow tor expansion and contraction. These tubes are open at the outer ends and are formed of a suitableelectrical insulating material which, will 'stand' extremely high of the radiator to direct the steam generated in saidboiler into the pipe 3. 11 1s the feed water pipe leading to the boiler and here shown connected to, the bottom of the radiator. The flow of water to the boiler is controlled by a float valve 12 of any suitable design. The valve 12 is here shown inside the boiler but may be otherwise arranged it desirable or necessary. The valve 12 is arranged to definitely control the inflow of water to the boiler and to regulate the high water level. A suitable gage glass may be arranged upon the boiler to determine thelevel of the water therein.

14' is a pipe leading from the top of the radiator downwardly and discharging into the boiler below the low water level. This pipe is provided with a suitable relief valve 15 to relieve any excessive pressure of steam.

16 is a. water supply pipe leading to the radiator from a suitable water supply and controlled by a suitablefloat valve 17 which maintains a constant level of water in the -'radiator.

part sectional elevational view of a heating 7 in the event of the temperature of the\ boiler rising above a certain predetermined point.

20 is a regulating thermostat arranged at any suitable point in the apartment electri ,cally connected by wires 19 to the contact box 9 and arranged so as to. cut in and cut out the current to the boiler according to the fall and rise of the temperature in the apartment.

In the use of this device the individual equipments are installed in the desired position and when in is desired toheat the apartment the electriccurrent is turned on. The electric heating element at once commences to heat the tubes in the small tubular boiler and as the level of the water within the boiler is maintained by reason of the float valve therein so as to just cover these tubes, the Water therein will be heated very quickly and converted into'steam. The steam rising to the top of the boiler passes into the pipe 10 and flows through the pipe 3 into the radiator quickly heating the same. -The steam inpassage through the pipe 3 transmits a certain amount offbeat to the Water in the bottom of the radiator and is itself partly condensed and the condensed steam mingles with the Water in said radiator assisting in raising its temperature.

The temperature of the Water in the radiator is raised very quickly, consequently the heating value of the plant comes into opera-.

The operation of the electrical controlling contacts are not herein shown or described as such devices are common. The 'electrlc circuits are so arranged aslto pass throughthe circuit to the safety thermostat 18 on the boiler so that in the event of the Water supply to the boiler failing or in the event of the steam pressure rising to too high a point, the said thermostat will cut out the current.

An equipment such as described forms a complete unit so that the heating of the indi- F vidual apartments can be controlled independently and all the heat generated is directly ,applied. The maintenance of the room temperature is automatically controlled and the device is rendered perfectly safe in operation. g

The boiler herein shown is of the tubular type With electric heating elements arranged in the tubes but it must be understood that other forms of boiler or heating element may be used if desired.

What We claim as our invention is 1 A heating system, comprising, a radiator, a Watersupply connected to said radiator, means foramaintaining a constant level of Waterv in the radiator, a steam boiler, a

a steam pipe leading from said boiler said radiator and extending above the high Water level therein, a Water supply to said boiler, means for automatically regulating the level of Water in said boiler, means for heating the water. in said boiler, and automatic means forcontrolling said heating means.

2. A heating system, comprising, a radiator, a.-Water supply connected to said radiator, automatic means for maintaining a constant level of Water in the radiator, a'

steam boiler, a Water supply pipe leading from said radiator to said boiler, means for automatically controlling the level of Water in said boiler, a steam pipe leading from said boiler to said radiator and extending above the high Water level therein, means for heating the Water in said boiler, and automatic means for controlling said heating means. v

3. A heating system, comprising, a radiator, a Water supply connected to said radiator, automatic means for maintaining a constant level of Water in the radiator, a steam boiler, a water supply pipe leading from saic radiator to'said boiler, means for automatically controlling the level of water in said boiler, a steam pipe leading from said boiler to said radiator and extending above the high water level therein, means for heating the Waterin said boiler, a thermostat arranged on said boiler above the high Water level, means operated by said thermostat for cutting out said heating means on an excessive rise in temperature, and automatic means for regulating said heating means.
